BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to, for example, a Japanese word processor to display document data such as characters and figures input from an input means on a display means and to print the document data by a printing means. The present invention relates to a document processing device that prints on recording paper.

[0002]

2. Description of the Related Art Conventionally, a Japanese word processor generally inputs document data such as characters and figures from a keyboard and outputs the document data to an LCD (Liquid Crystal Displa).
The Japanese document is created by displaying it on the display screen such as y). Some of such Japanese word processors, like the device disclosed in Japanese Patent Laid-Open No. 2-269078, print document data on recording paper by a printer provided as a constituent member thereof.

The printer described above, as shown in FIG.
By moving the carriage 22 carrying the ink ribbon cassette 20 and the recording head 21 back and forth, it is possible to print on the recording paper in the lateral direction and the platen roller 23
By conveying the recording paper in accordance with the rotation of, the printing can be performed in the vertical direction on the recording paper. In addition, the printer is
The longitudinal and lateral dimensions of the recording paper are measured by scanning the recording paper in the vertical and horizontal directions by a recording paper sensor 24 provided at a portion of the carriage 22 facing the platen roller 23.

As a result, the above printer detects the printable range of the document data and displays the inputtable range of the document data corresponding to the printable range as a rectangular area on the display screen, thus Document data can be input and printed according to the size of the recording paper.

[0005]

However, the vertical and horizontal dimensions of the recording paper are measured by the recording paper sensor as in the prior art,
In a printer that detects the printable range of document data, each line on the recording paper is treated as having the same printable width, and the left end of the recording paper on the format The coordinates are fixed at a certain point on the printer, and in order to take the left margin accurately, it is necessary to load the recording paper at the exact point.

Therefore, when the recording paper has a non-rectangular shape, a recording paper is punched, or a non-standard recording paper is used, or the recording paper is displaced from a desired feeding position. In this case, the printing result is different from the desired printing result, such as the printing result protruding from the recording paper, or the left margin on the recording paper cannot be provided as set.

Further, in order to prevent the above-mentioned print result from protruding, if a large margin is left and right on the recording paper, it is not possible to print up to the both ends of the recording paper, which causes uneconomical printing of document data. It has a problem of being invited.

[0008]

In order to solve the above-mentioned problems, the document processing apparatus according to the first aspect of the present invention displays the document data such as characters and figures input from the input means on the display means. At the same time, the following means are taken in the document processing apparatus for printing the above document data on the recording paper by the printing means.

That is, the print area detecting means for detecting the printable area of the document data on the recording paper, and the document data are stored in the printable area of the recording paper detected by the print area detecting means with a predetermined margin. A printing control unit that controls the printing unit to print is provided.

In order to solve the above-mentioned problems, the document processing apparatus according to the second aspect of the invention has the following means in the document processing apparatus according to the first aspect.

That is, display control means for controlling the display means is provided so that the printable area of the recording paper excluding the predetermined margin corresponds to the inputtable area of the document data.

[0012]

According to the structure described in claim 1, a predetermined margin is provided by detecting the printable area of the document data on the recording paper by the print area detecting means and then controlling the print means by the print control means. In this state, the document data is printed in the printable area. Therefore, even when a non-standard-sized recording paper is used or the recording paper is loaded while being displaced from a desired paper feeding position, reliable document data printing can be brought with a predetermined margin.

According to the second aspect of the invention, by controlling the display means by the display control means, the area excluding the predetermined margin from the printable area of the first aspect can be input with the document data. It is displayed on the display means in association with the area. Therefore, it is possible to input and edit the document data using the display means in association with the printable area of the recording paper.

As shown in FIG. 2, the ROM 2 has storage areas 2 for programs, font data, and dictionaries.
As shown in FIG. 3, the RAM 3 is provided with recording areas 3a to 3d for format information, document data, print data, and other works.

Further, the CPU 1 has an LCD (Liquid) which is display means for displaying document data such as characters and figures.
A Crystal Display) 5 and a printer 6, which is a printing unit for printing document data, are connected via a display control unit (display control unit) 7 and a print control unit (print control unit) 8, respectively. The LCD 5 is controlled by the display control unit 7 to set formats such as line feed width and character spacing on the display screen.

In the printer 6, the print controller 8 operates the components of the recording head 9, the X and Y motors 10 and 11, the head up / down motor 12, and the recording paper sensor (printing area detecting means) 13. It is controlled. The recording head 9 is composed of a thermal head for thermal transfer. In addition, the recording paper sensor 13
Is a reflection type photo sensor or the like, and the platen 18 has a reflectance difference between the surface of the platen 18 (usually black or the like and low reflectance) and recording paper (usually white or the like or high reflectance) which will be described later. The presence or absence of the recording paper above is detected.

By the way, the printer 6 has an ink ribbon cassette 14 containing a thermal transfer ink ribbon 14a, as shown in FIG.
The ink ribbon cassette 14 is provided with a carriage 15 which is detachably mounted by an engaging projection 15a.

The carriage 15 has the recording head 9 and the recording paper sensor 13 arranged at the front end portion of the upper surface on which the ink ribbon cassette 14 is mounted. As a result, when the ink ribbon cassette 14 is mounted on the carriage 15, the ink ribbon 14a is moved to the carriage 1
The ink ribbon 14a is wound around the left and right spools 15b and 15b on the upper side of the recording medium 5, and a part of the ink ribbon 14a is exposed and arranged in front of the recording head 9. The recording head 9 and the recording paper sensor 13 are the same as those of the carriage 1.
5 is fixed by being offset by a predetermined value C in the horizontal direction of the recording paper.

Further, the carriage 15 has a sliding portion 15c formed at the lower end on the front side on which the recording head 9 is arranged, and a guide shaft 16 is inserted through the sliding portion 15c. On the other hand, on the rear side of the carriage 15, the X
The rack member 17 is provided in a meshed state with a drive gear (not shown) of the motor 10. As a result, the carriage 15 slides along the guide shaft 16 as the X motor 10 is driven so that printing can be performed in the lateral direction on the recording paper.

A platen 18 and a paper feed roller 19 are disposed in front of the carriage 15 in parallel with the axial direction of the guide shaft 16. The platen 18 is
The recording paper is sandwiched between the recording head 9 and the ink ribbon 14a when the recording head 9 is driven.

The paper feed roller 19 is provided so as to be rotatable with the driving of the Y motor 11. This allows
The paper feed roller 19 described above prints the recording paper in the ink ribbon cassette 1 so as to enable printing in the vertical direction on the recording paper.
4 and the platen 18 are conveyed.

The operation of the document processing apparatus having the above-mentioned structure will be described below.

FIG. 5 shows a flow of format setting and document input before print processing. In S1 and S2, the input from the keyboard 4 is read, and if the standard recording paper is selected, the process proceeds to S6.
Otherwise, the process proceeds to S3. In S3, loading of recording paper is prompted, and in S4, the line feed width and character spacing are set. In S5, the carriage 15 is scanned along the platen 18 and the coordinates of the recording paper portion of each line are measured.

As detailed processing steps in S5, as shown in the flowchart of FIG. 6 and the explanatory view of FIG. 9, in S51, S52, and S53, the recording paper sensor is moved while moving the carriage 15 step by step. Thirteen
Coordinates obtained by adding the offset amount (predetermined value C) between the recording head 9 and the recording paper sensor 13 to the point where the recording paper detection signal from (4) changes. Here, the "one step" of the carriage movement is the movement amount for one printing dot. And S5
When the scanning for one line is completed in 4, the line feed is returned with the line feed width W set in S4 (S55), and the above process is repeated until the lower end of the recording paper is detected in S56. After that, when the measurement for one sheet is completed, the recording paper is rewound to the position where the recording paper is initially loaded in S57. In FIG. 9, the recording paper scanned by the recording paper sensor 13 is illustrated as a circular non-standard recording paper.

Next, in S6, in the case of the standard recording paper, the inputtable area E of the number of lines and the number of digits calculated with the line feed width and the character spacing as the predetermined default values is displayed on the screen of the LCD 5.
(See FIG. 10.) On the other hand, in the case of non-standard size recording paper, the inputtable area E is calculated from the set line feed width, character spacing, and measured coordinates of the recording paper part, and the format is set for each line. Then, according to the format, the inputtable area E is displayed on the screen of the LCD 5. (Refer to FIG. 11) The inputtable area E shown in FIG. 10 and FIG.
Under the control of the display controller 7, the printable area detected by the recording paper sensor 13 is set to an area excluding a predetermined margin, and the input impossible area is displayed as a dot on the screen of the LCD 5. It has become so.

Next, in S7, character input and editing work are performed by a known procedure. In the case of non-standard size recording paper, the printable area of only one recording paper can be measured at a time, so the editing work is only for one page. During editing, the entire page may be represented by a frame, and the layout of the document may be displayed by dots or rectangles inside the frame. After that, when the document format is changed during editing in S8, the format is changed while the document data is left (S9), and in S11, if the recording paper is a fixed recording paper, go to S6, and if it is a non-standard recording paper, go to S3. Return. When the print mode is selected during editing (S1
0), and shifts to S12.

In the case of the standard recording paper in S12, S1
In step 3, the recording paper is set and the process shifts to the printing process A. On the other hand, in the case of the non-standard size recording paper, the process shifts to the printing process B as it is.

Next, the print processing A, which is the print processing on the standard recording paper as described above, will be described below with reference to the flowchart of FIG.

First, S14 and S15 are repeated, and the carriage 15 is moved rightward step by step until the recording paper is detected. In S16, the carriage 15 is moved to the right by the offset (predetermined value C) between the recording head 9 and the recording paper sensor 13 from the position where the recording paper is detected for the first time, and is stored as the left end coordinate of the recording paper.

In S17 to S24, the printing operation for one line is performed. In S17, from the portion without the recording paper to the recording paper portion,
Alternatively, the carriage movement amount after passing the opposite portion is counted. S18 and S19 are processes for absorbing the offset between the recording head 9 and the recording paper sensor 13, and the value counted in S17 is compared with the offset. In S22, print data for one step is printed. In S23, the print data for one step is discarded without being printed. Here, the “print data” is dot-unit data sent to the recording head 9.

S17 → S18 → S20 → S22 → S24
In the case of shifting in the order of, the process for printing in the middle part of the recording paper is performed. S17 → S18 → S21 → S23 →
When shifting to the order of S24, the process for printing on the right side of the hole of the recording paper is performed in S17 → S19 → S20 → S2.
When the sequence proceeds from 2 to S24, the process for printing on the right edge of the recording paper and the left side portion of the hole in the recording paper is performed.
Further, in the case of shifting in the order of S17 → S19 → S21 → S23 → S24, the process is performed on the part without the recording paper.

In S25, a line feed process is performed when the print data for one line is exhausted, and in S26, it is checked whether or not the print data for one page is completed.
The process proceeds to step S27 to perform page break. If not, the process proceeds to step S27 to move the carriage 15 to the left end of the recording paper stored in step S16, and then to step S17.

In step S29, it is checked whether the document is at the end. If it is the end, the process is terminated. If not, the process proceeds to step S14 to print the next page.

Next, the print processing B, which is the print processing on the non-standard-size recording paper as described above, will be described below with reference to the flowchart of FIG.

In the case of the print process B, since the left edge position of the recording paper is known when measuring the printable area, there is no part corresponding to S14, S15, S16 and S27 of the print process A. Further, since the non-standard size recording paper can print only one page, the processing is ended when the printing of one page is completed. Therefore, there is no portion corresponding to S28 and S29 of the print process A. Therefore, in S30 to S39 which are the process steps of the print process B, S17 to S2 of the print process A are performed.
The same process as 6 is performed.

As described above, the document processing apparatus of this embodiment stores the document data with the recording paper sensor 13 for detecting the printable area of the document data on the recording paper and the predetermined margin in the printable area. In order to print, the print control unit 8 that controls the printer 6 and the printable area other than the predetermined margin are set to L in order to correspond to the inputtable area of the document data.
The display controller 7 for controlling the CD 5 is provided.

For this reason, since the presence or absence of the recording paper is always detected during printing, the platen 1 can be used even when the fixed recording paper with holes is loaded or when the recording paper loading position has an error.
8 can be prevented from being erroneously printed. As a result, it is possible to print on both ends of the recording paper. In addition, the width of the recording paper is measured line by line prior to editing the document, and the area where the document data can be input is displayed for each line. However, printing can be performed without protruding from the recording paper. Also for the standard size recording paper, the coordinates of the left edge of the recording paper are obtained for each page and printing is performed based on the coordinates, so that an accurate printing position can always be obtained.

[0040]

As described above, in the document processing apparatus according to the first aspect of the present invention, the print area detecting means for detecting the printable area of the document data on the recording paper, and the recording detected by the print area detecting means. The print control unit controls the printing unit so that the document data is printed in the printable area of the paper with a predetermined margin.

As a result, even if a non-standard size recording paper is used or the recording paper is loaded while being displaced from a desired paper feed position, reliable document data printing can be brought about with a predetermined margin. Therefore, it is possible to provide a convenient document processing device that enables accurate printing results and easy paper feeding.

Further, by preventing erroneous printing on a recording sheet other than the recording paper due to the above-described accuracy of the printing result, it is possible to protect the constituent members such as the recording head and the platen constituting the printing means from the deterioration due to the malfunction. There is an effect that can be.

According to a second aspect of the present invention, in the document processing apparatus according to the first aspect, the printable area of the recording paper excluding a predetermined margin is displayed so as to correspond to the inputtable area of the document data. This is a configuration including display control means for controlling the means.

Thus, since the input and editing of the document data using the display means can be performed in correspondence with the printable area of the recording paper, the document in consideration of the print result on the recording paper can be obtained. The effect is that it can be created.
